Select Data from different Datasource

Hello,
there is a Fusion Web Application with one Application Module which is based on "Database Server 1".
For calculation of the Values Database 1, I need to get Data (DB Table) from "Database Server 2".
How to get the values (Table) from Database 2 in the same project?
(Do I need to have a second Application Module maybee?)
Thank you in advice.

Hi,
below is my Model.jpx file:

Select data from different database

hi,
may I know how to select data from different database?
for example,
I've 2 databases, OracleDB and OracleAR
Connect with OracleAR in SQL*Plus
select * from OracleDB.TableName
does Oracle support this kind of query?
how can I retrieve data from other database while im connecting with
other database?

Hi,
Yes, it's possible. No, your syntax won't work.
First of all you have to define a DATABASE LINK inside the DB where you are already connected (in this case OracleAR). Read docs how to do that.
Second thing is the query. It will look like
SELECT * from TableName@<NameOfDatabaseLink>Greetings,

Data from Different datasources in the same table

Hi everyone,
Here I am under this complex problem.
I have two different Bapi's which are being called multiple times.
These bapi's have 3 common export parameters. I need to display a table with these 3 common export parameters (columns), as columns and two other custom columns.
Data in custom colums needs to be filled based on the the 3 original columns with some logic build over these 3 columns.
All the data returned under these columns is to be accumulated and showed in the frontend in a table.
Any ideas.. how will you handle this in the context of controllers and UI table.
Do I need to create a dictionary element?
Please help..
Thanks,
Amber

Hi Amber,
In your context, create a value node with 3 value attributes for the BAPI output params with the exact same name as the BAPI params. Then you can use the WDCopyService class to copy the corresponding fields.
For the two custom columns, create 2 calculated attributes in the same value node. The WD framework will generate setters and getters for these attributes. In the setter method write the logic for calculation of these attributes.

Select data from database tables with high performance

hi all,
how to select data from different database tables with high performance.
im using for all entries instead of inner joins, even though burden on data base tables is going very high ( 90 % in se30)
hw to increase the performance.
kindly, reply.
thnks

Also Check you are not using open sql much like distict order by group by , use abap techniques on internal table to acive the same.
also Dont use select endselect.
if possible use up to n rows claus....
taht will limit the data base hits.
also dont run select in siode any loops.
i guess these are some of the trics oyu can use to avoid frequent DATA BASE HITS AND ABVOID THE DATA BASE LAOD.

Fetching data from multiple datasources

Awaiting kind advise.

Hi
There r no prerequisites to your requirement . How ever we have different data flows for your requirement as 1. multiple data source to different info sources or transformations to a single cube 2. multiple data sources to single info source or transformation to a single info cube . Any way regarding data flow complexity , second approach is easier one ......

Data from different databases in the same report.

Hi Everyone,
I am trying to build a reconciliation report in which I need to show the data from the source and target, side by side.
Source and target are both different databases, although being oracle only
Whenever a new data model is created, it gets attached to a data source and in the report we need to choose a specific data model.
Can we have data from different databases in the same report ?

Yes, it is possible.
One way Is to use dataTemplates. There you can make queries from any number of different databases (The max I have done is 5).
It looks something like that:
<dataTemplate name="NameOfTemplate">
<dataQuery>
     <sqlStatement name="Q1" dataSourceRef="Connection1">
          <![CDATA[     select * from table1]]>
     </sqlStatement>
     <sqlStatement name="Q2" dataSourceRef="Connection2">
          <![CDATA[     select * from table2]]>
     </sqlStatement>
</dataQuery>
<dataStructure>
     <group name="RESULT1" source="Q1">
          <element name="P_FIRST_NAME" value="P_FIRST_NAME"/>
     </group>
     <group name="RESULT2" source="Q2">
          <element name="P_DATE" value="P_DATE"/>
     </group>
</dataStructure>
</dataTemplate>dataStructure is very important when you get data from different places, if you don't define those elements, then only the result from Q1 is shown.
The second possible way is to make as two different data models, each containing their own query and then set Main Data Set as concatenated SQL Data Source.
Best of luck,

How to display multiple data from different table in one table? please help

Hi
I got sun java studio creator 2(the separate installation not the one in the net beans)....
My question is about displaying data that have been taken from the database.... I know how to display data in a table(just click on the table "bind data" )... but my question is that:
when i want to use a sql statement that taken the data from different table...
how can i display that data in the table(that will be shown in the web) ??? when i click bind data on the table i can only select one table i can't select more than one....
Note:
1) i'm using the rowset for displaying the data in the table, since the sql statement is depending on a condition(i.e. select a from b where c= ? )...
2) i mean by different table is that( i.e. select a from table1,table2 )..
thanks in advance...

I want display the details of emp table.. for that I am using this SQL statement.
select * from emp where mgr=nvl(:mgr,mgr);
when I give the input as 7698 it is displaying the corresponding records... and also when I won't give any input then it is displaying all the records except the mgr with null values.
1)I want to display all the records when I won't give any input including nulls
2)I want to display all the records who's mgr is null
Is there any way to incorporate to include all these in a single query..It's a little unclear what you're asking.
The following query always includes rows where mgr is NULL, and when the bind variable :mgr is NULL, it displays all rows:
SELECT *
FROM     emp
WHERE     LNNVL (mgr != :mgr)
;That is, when :mgr = 7698, it displays 6 rows, and when :mgr is NULL it displays 14 rows (assuming you're using the Oracle-supplied scott.emp table).
The following query includes rows where mgr is NULL only when the bind variable :mgr is NULL, in which case it displays all rows:
SELECT     *
FROM     emp
WHERE     :mgr     = mgr
OR      :mgr      IS NULL
;When :mgr = 7698, this displays 5 rows, and when :mgr is NULL it displays 14 rows.
The following query includes rows where mgr is NULL only when the bind variab;e :mgr is NULL, in which case it displays only the rows where mgr is NULL. That is, it treats NULL as a value:
SELECT     *
FROM     emp
WHERE     DECODE ( mgr
            , :mgr, 'OK'
            )     = 'OK'
;When :mgr = 7698, this displays 5 rows, and when :mgr is NULL, it displays 1 row.

Select data from ORacle in an orchestration

I am looking for an example of orchestration with two way send port. The orchestration should select data from an oracle DB using input to orchestration. Based on the query results, orch has different paths to follow.
Can someone please point me to an example/sample or let meknow what is the best way to do it?
Thanks in advance.

Hi ,
You can go ahead with Oracle Polling which have a select statement against the DB.
There is a good post from Bali which i am listing below

SELECT data from two databases

I have two databases that I need to select data from in a
single SELECT. Using DWs Advanced window for creating the select I
don't see any way to select more than 1 Connection. Both databases
have unique user and passwords but reside on the same server. Any
idea how I can write a single SELECT to get data from both dbs. I
assumed it would be similar to selecting data from multiple tables
within the same db but the connection part is stumping me. Any
ideas would be greatly appreciated.

That's the basic technique for joining two tables in the same
database.
The original poster has tables in different databases that
have
different user accounts and passwords.
Although it's possible to join two databases, you cannot do
it unless
you have one user account with the same privileges on both
databases.

Select data from all the table names in the view

Hi,
"I have some tables with names T_SRI_MMYYYY in my database.
I created a view ,Say "Summary_View" for all the table names
with "T_SRI_%".
Now i want to select data from all the tables in the view
Summary_View.
How can i do that ? Please throw some light on the same?
Thanks and Regards
Srinivas Chebolu

Srinivas,
There are a couple of things that I am unsure of here.
Firstly, does your view definition say something like ...
Select ...
From "T_SRI_%"
If so, it is not valid. Oracle won't allow this.
The second thing is that your naming convention for the
tables suggests to me that each table is the same except
that they store data for different time periods. This would be
a very bad design methodology. You should have a single
table with an extra column to state what period is referred to,
although you can partition it into segments for each period if
appropriate.
Apologies if i am misinterpreting your question, but perhaps
you could post your view definition and table definitions
here.

Single query to get data from different databases

i need to capture certain fields from certain tables in database 1 and certain fields from certain tables in database 2 into one file using a single SQL statement.
i tried searching on the net
i found that dblinks can help
but iam not sure if ill be able to create dblinks in my situation which is:
i need to get data from oracle to be copied to mysql
this is not a replication acitivity, but i need certain fields from one database and certain from the other
so what iwas thinking is, if i use an sql query to get all the fields (i need around 40) from the different oracle databases and create a singlefile with one insert per select, i can then read that file into mysql
instead of creating multiple sql queries for each table and creating separate files and eventually separate tables in mysql.
can anyone help me here?
or maybe suggest another approach.
thanks

Hi,
I think dblink is the only option available to get data from different databases. It will work for your case too.
CREATE DATABASE LINK db_link CONNECT TO user_name IDENTIFIED BY password USING 'instance_name'you must have the system privilege 'create database link' to create db links. This way you can get the required data and put it in a table in oracle. But i dont know how to put this data from oracle table to Mysql.

Retriving of data from different tables

retriving of data from different tables depening of the primary key this key field is there in all tables if it is there in one v table it should continue to other tables otherwise it should get exit from that it should display information message or otherwise success message if it is there in all tables .

Im writing the concept, just check it.
SELECT * from kna1 into lt_kna1.
if sy-subrc eq 0.
selest * from lfa1 into lt_lfa1
for all entries in lt_kna1.
endif.

Selecting datas from tables where tbale name is store in a row

Hi
I need to select datas from several different table (QE01, QE02, QE06, QEXXetc.).
The code of the tables I need to select from is store in another table.
Here's an example:
In the table JOURNAL, I have several entries:
01
06
21
31
These are the codes of the tables I need to select datas from:
QE01
QE06
QE21
QE31
I can't use variables in here, how could that be done ?

Hi,
This should not be a question on how to query data, but rather on how to store them.
You did not mention any version, but I suggest you read about partitioning,
http://download.oracle.com/docs/cd/E11882_01/server.112/e25789/schemaob.htm#CNCPT112
Could be that especially exchange partition is interesting.
My guess is that these tables are created on the fly as part of data loads?
If so, complete that ETL process by exchanging the just loaded data into a partioned table. And your problem of what to query has disappeared.

Fetch data from different tables print them is assigned places

Hi Friends,
I have designed one SMART-Form (Receipt).
I need to fetch data from different tables and the data must be print in assigned places. Please help me how to achieve this requirement. Thanks for your help.
Best regards,
Manju.
Edited by: Alvaro Tejada Galindo on Feb 12, 2008 10:20 AM

U're right.
When it creates a smartform it needs to decide when the main data have to be extracted:
- or in driver program
- or in smartforms
The difference can be in the performance, because the program can select the data only once, the smartforms needs to extract them everytime it's called.
I prefer to use a complex structure for the smartform interface as so all data I need are in only one structure, the problem is the complex structure is harder to be managed.
